Patented Dec. 12, 1.916.

Divided and this application filed November 5, 1913` Serial No. 799,392.

To all 'ui/1,0m t r11/(Ly (.fonccrn:

Be it known that I, Henny l.\1.-\Y'iiun"i', a

citizen of the United States, and resident .vof Bridgeport, coiinty of Fairfield, and State of Connecticut, have invent-edan Improvement in Lamps, of which the following description, in connection with theacconipanying drawings, is a specification, like characters on the drawings representing like parts.'

This invention relates to lamps, and more particularly to acetylene -lainps in which the lampV body and gas generating parts are combined in a single portable apparatus The present application is directed to subject matter divided ontof my copending application for acetylene lamps Serial No.

715,783, filed August 19,1912.

The character of the invention mayl be best understood by reference to the 'following description ot-an illustrative embodiment thereotl shown inthe. accompanying' drawing,A wherein 1 lFiguize 1 is a plan of an illustrative lamp en'ibodying the invention partially broken ziway to disclose certain parts thereof in Section; and l `ig.,2 is a side elevation of the lampshown in Fig. 1 partially broken away to disclose the parts in section.

Referring to the '-di'awing, the illustrative :acetylene lainp shownl therein as embodying fthe invention comprises a gas generator 1 ,consisting of a water reservoir 3 and a genl erator cup 5 detachably conucctedto the water reservoir as by a bayonet joint or threaded connection. Connected to the gas generator 1 is a lamp body 7 provided with a burner, a reiector 9, side lights 11 and other elements of usual construction. Be-

10 tween the cup 5 and the water reservoir 3 is a gas supply portion 13 communicating with the burner of the lamp through a supply pipe. 15 connected to the lamp at a point beneath the latter.

i5 In lamps where the lamp body is offset from the generator it frequently happens that thel user will unscrew the detachable cup 5 by seizing the cup with one hand and the outer end of the lamp body with the `0 other. thereby tending to twist the lamp' body on the generator and tending to break; ott' or injure the pipe connection 15 when such connection is so located as to receive tlv` twisting strain. To avoid any possibility (1f-such occurrence a connection is inkel'- posed between the laiin` body and generator which will tend to take this twisting strain and relieve the pipe connection 15 there- .t1-om. ln the embodiment of the inventionshown herein such connection i s in the form,

ing member-or ,backing lfor. the lamp body upon he generator, thereby [neventing any tend y of tlie'lamp body to rock or. 11i-,ove

l with o'r about the'pipe connection l5. This seating member, in connection with the pipe connection 15, may provide a 'sufficient-ly rigid connection for Ithe llamp body to the. generator, but to add to the security of the i connection 'the baclcl) of the lanip'bodymay be rigidly attached to the 'water reservoir by a threaded member or screw 2l having a flanged head overlying the'baclr 19 and its shank entered apertures in said back 19 and the wallof the water -reservoir. This screw projects in somewhat beyond lthe wall `of the waterreservoir and receives a Suitable coperating member such as the anged nut 23 preferably seated in a recess in the wall ofsaid reservoir. lVlien the nut is setnp on said screw it will securely clamp the lamp back '19 against the wall of tlie'reservoir and also secure the seating member in place between them. thus drawn togetherthe member lbecausc of its flared edge, clearly shown in the figures, will tend to be slightly sprung and thus forms a resilientwbracing connection throughout a circular area of 'which the screw is the center. Theconnection is consequently very lirui and there is'no lost motion. In fact the connecting member acts with respectto the screw very milch as The screw 21 may would -a lock washer. l also serve to .assist in holding the reflector 9 in place. To this end` said screw is tapped out to receive a member in. the. form of a screw 25 having a flanged head overlying tbc reflector 2) and securiugthe same against the ilangcd head of the screw 21;-

When the lamp and reservoir are lthrough registering Having described one illustrative embodiment of the invention without limiting the same thereto, what I claim as new and desire to secure by Letters Patent is:

l. In a. lamp .the conibination of a. fuel containing portion with a lamp body offset at one side thereof; a supply pipe connecting said lamp body Iand said fuel containing tion portion; a central connecting melnber be'- tween said body and said portion and a seating mem'ber interposed between the saine and resiliently bracingthe same apart in a zone spaced from and surrounding said connection.

2. In a lamp the combination of a fuel containing portion with a lamp body Offset at one side thereof; a supply pipe connecting the lamp body and fuel containing por a curvilinear conformable seating member having an outwardly flaring edge to engage the lamp back and conform to the outline thereof between the lamp back and fuel containing portion whereby movement of the lamp body relatively to the fuel containing portion prevented; and means co operatixig with said seating member to lock the lamp body to the'fuel containing portion.

ln a lamp a combined body and reliector securing device for securing the san/ie to a support, comprising a` threaded member having a relatively wide hanged head, said member adapted to engage and extend through the lamp body and said support7 a cooperating n'iember to lock the threaded member therein. the threaded member being tapped, a second member extended through the reflector and threaded to the first named threaded member for locking the reflector to the flanged head of said member.

4. In a lamp the combination of a fuel containing7 portieri with a, lamp body offset at one side thereof; a supply pipe connecting the lamp body and fuel containing portion; a cup like, conformable seating member interposed between said containing portion and lamp body and having a bottom conforming to one of said members and a flared edge conforming to the other of said members and means cooperating with said seating member to lock the lamp body to the fuel containing portion.

In testimony whereof, I have signed my name to this specification, in the presence of two subscribing witnesses.V
